Assessment tools are essential in occupational therapy for providing client-centered care, clinical decision-making, evidence-based documentation, and defining expected outcomes. This study investigated available occupational therapy assessment tools for children and adolescents in Iran.

A comprehensive search was conducted in MEDLINE, PubMed Central, Web of Science, Embase, Scopus, SID, Magiran, and Google Scholar from their inception until May 24, 2022. Two reviewers screened records and applied inclusion criteria focused on peer-reviewed articles in English or Persian, covering children and adolescents aged 0-18 years old in Iran. The methodological quality of each study and the evidence quality of each measurement tool was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias Checklist, and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach.

A review of 66 articles published between 2010 and 2021, identified 51 assessment tools. The majority of tools (70.7%) targeted typically developing children and those with cerebral palsy, with limited options for adolescents (n=5) and infants (n=1). These tools primarily focused on assessing body functions (47.06%), particularly sensory-motor functions. While numerous tools demonstrated good reliability (66.67%) and significant content validity (31.37%), there was a paucity of high-quality evidence supporting other psychometric properties.

This study identified 51 occupational therapy assessment tools for Iranian children and adolescents. However, the present research identified some concerning trends, such as lack of tools available for specific populations, an overreliance on translated tools, and a predominant focus on body functions. Moreover, there were concerns about the methodological quality of studies using these tools.

Adaptation to complications of hysterectomy is one of the topics of concern for women and health care providers. There is no instrument for evaluating adaptation to hysterectomy. This study aimed to design the Hysterectomy Adaptation Scale (HAS) and assess its psychometric properties.

This methodological study was conducted from 2018 to 2020 in Mashhad, Iran. To develop the item pool, qualitative data from directed content analysis and data from the review of adaptation and coping instruments were used. The face, content, construct validity, internal consistency, and stability were used to evaluate the psychometric properties of HAS.

The final version of the HAS consisted of 24 items with a reported content validity index of 0.9. Six factors were extracted from the principal component analysis, which explained 60.3 of the observed variance. Model fit indices in confirmatory factor analysis showed that the model was well fitted. The values of the alpha coefficient and intra‑class coefficient were 0.86 and 0.95, respectively.

The HAS is a valid and reliable scale for evaluating the adaptation level of hysterectomized Iranian women. HAS can distinguish between hysterectomized women who have adapted to hysterectomy and those who have not. It can be used to assess the adaptation of hysterectomized women in research and clinical practice.

This study is done to determine the translation and psychometric properties of the Persian version of Neonatal Intensive Care Unit Parental Belief Scale (NICU‑PBS) in Iranian parents.

The present study was conducted by the descriptive cross‑sectional method. This research was conducted from January to August 2021. The population included all parents whose infants were hospitalized in NICUs of two university‑affiliated hospitals (Kermanshah University of Medical Sciences and Shiraz University of Medical Sciences). Out of them, 291 subjects were selected by the purposeful sampling method. The utilized questionnaires included a demographic information form, NICU‑PBS, Beck Depression Inventory, and Maternal role adaptation scale. The descriptive statistical indexes, Cronbach’s alpha, intra‑class correlation coefficient, and Pearson’s correlation coefficient were used for data analysis. Also, to evaluate the construct validity of the NICU‑PBS, we used Confirmatory Factor Analysis (CFA).

The participants included 97 fathers (33.33%) and 194 mothers (66.67%). According to the CFA results, the three‑factor model NICU‑PBS (confidence in the parental role, parent–child interaction, parental knowledge of the NICU) was approved in Iranian parents (χ2/df = 1.79; p </em>< 0.001; GFI = 0.91; AGFI = 0.89; CFI = 0.91; RMSEA = 0.05). NICU‑PBS with BDI‑II (r = ‑0.42) has divergent validity, and material role adaptation (r = 0.46) has moderate and acceptable convergence validity (p </em>< 0.01). The results of Cronbach’s alpha for the total NICU‑PBS were 0.85.

The results demonstrated the proper and acceptable validity and reliability of NICU‑PBS among Iranian parents.

The development of societies relies on the type and manner of activities performed at universities. Professors play a pivotal role in the development of universities and societies. Assessment of professors’ motivation and behavior and factors affecting them can improve the educational system and increase its performance. This study aimed to assess the validity and reliability of the Physician Teaching Motivation Questionnaire (PTMQ) from the viewpoint of clinical professors at Iran University of Medical Sciences (IUMS).

This is an instrument psychometric study in which the questionnaire’s validity was determined through the face and content validity and its construct validity through exploratory and confirmatory factor analysis. Reliability was determined through the calculation of Cronbach’s alpha and intraclass correlation coefficient and consistency between agreers. The data were analyzed in SPSS 23 and LISREL 8.8.

The results showed that all 18 items had acceptable content validity (0.68-0.97). The Cronbach’s alpha and intraclass correlation coefficients were 0.81 and 0.86, respectively. The number of items remained unchanged at 18 according to exploratory factor analysis which classified them into six categories (intrinsic motivation, identified motivation, introjected motivation, career motivation, external motivation, and teaching assistant motivation) and explained 54% of the total variance of the mentioned variables. Also, the value of CFI was equal to 0.93 and the value of Cohen’s kappa was between 0.77 and 0.84.

The Persian version of PTMQ is a valid and reliable instrument that can be used for research, educational, and practical purposes to evaluate the teaching motivation of clinical professors in other groups.

The urgent need and craving for smoking are significant aspects of smoking cessation syndrome, often leading to high relapse rates. Therefore, evaluating smokers’ cravings and immediate needs is essential, and the questionnaire on smoking urges (QSU) is a remarkable instrument for this purpose. 

This study aimed to evaluate the reliability and validity of the Persian version of QSU among the general population.

This is a descriptive cross-sectional study. The studied population includes 200 smokers from the general population referred to Shafa Hospital, Rasht City, Iran, in 2023. The QSU was translated and reviewed by translators and bilingual experts to achieve the final Persian version. We assessed the content validity, reliability, and factor analysis of QSU. The IBM SPSS software, version 26 was used for data analysis. In addition, confirmatory factor analysis was performed using Smart PLS software, version 3.2.9.

The results showed that the content validity rate was 0.94. The QSU exhibited a Cronbach α of 0.892, indicating high internal stability of the scale. After presenting the confirmatory factor model, 2 questions from the first factor and 4 questions from the second factor were removed due to their factor loadings of <0.3. The factor loadings of the items of the QSU in the first subscale were between 0.353 and 0.787 and in the second subscale were between 0.248 and 0.706. 

This study showed that QSU is reliable for measuring the “urgent need to smoke” in the Persian-speaking community.

Assessing life skills in children is a preventive approach to promoting their mental health and quality of life. Regarding the lack of appropriate tools, this study aimed to develop and validate a children's Life Skills Questionnaire (LSQ). 

In this cross-sectional study in the academic year of 2022-2023, the target population included all seven-year-old children in Kerman City, Iran. Initially, the preliminary questions of the questionnaire were prepared through interviews. Then, using a cluster sampling method, 1140 seven-year-old children from different schools in Kerman were selected. We determined the validity of the questionnaire using face validity, content validity, and construct validity methods. Also, we determined the reliability of the questionnaire using internal consistency and test-retest methods. We identified the optimal cut-off point aiding Receiver Operating Characteristic (ROC) curve analysis and the Youden Index. 

The LSQ for children had acceptable face and content validity, qualitatively and quantitatively, although some questions needed revision. The confirmatory factor analysis revealed that the questionnaire comprised 29 questions and six factors. Confirmatory factor analysis also confirmed the six-factor model. Cronbach's alpha for the scale was 0.86, and its dimensions ranged from 0.71 to 0.92. The cut-off point 100 with a Youden Index of 82.10% has the highest accuracy. 

Based on the findings, the life skills questionnaire can assess the life skills of seven-year-old children.

Suicide is an important health issue nearly all over the world. The Columbia Suicide Severity Rating Scale (C-SSRS) is a well-known instrument for suicide risk assessment. Our purpose in this study is to provide a Persian version of the C-SSRS and evaluate its psychometric properties in the Iranian military population, particularly suicide risk leveling characteristic of the C-SSRS.

For linguistic adaptation, we gathered opinions of an expert panel consisting of 23 professionals in mental health sciences. Furthermore, this version was administered to two groups of soldiers, one representing a sample of normal population (N = 338), while the other group comprised a sample of clinical population from a referral psychiatric hospital (N = 348) in Tehran, capital of Iran, from July 2021 until one year later. Besides the C-SSRS, the Beck Scale for Suicidal Ideation (BSSI), Beck Hopelessness Scale (BSS), and General Health Questionnaire 28 (GHQ28) were obtained from the participants. Correlation coefficients, internal consistency, and factor analysis were evaluated using the Statistical Package for the Social Sciences (version 23) software.

All items of the Persian version of the C-SSRS had acceptable content validity and face validity. This tool demonstrated high correlation coefficients with the BSSI (r = 0.73, P < 0.001) and BHS (r = 0.64, P < 0.001), but a low correlation coefficient with the GHQ28 (r = 0.22, P < 0.001). Specifically, the suicide risk level based on the C-SSRS had a high correlation with both the BSSI and BHS. Also, its internal consistency was satisfactory (Cronbach's alpha = 0.89). Furthermore, factor analysis revealed two factors that is consistent with suicidal ideation and suicidal behavior factors.

Our results indicated acceptable validity and reliability for the Persian version of the C-SSRS, demonstrating its capability to classify suicide risk. It can be concluded that the ordinal suicide risk level (as red, orange, yellow and green) is a valid index for the application of the C-SSRS.

This current study aimed to validate the Indonesian version of the Inventory of Statements About Self-Injury (ISAS) questionnaire, which provides a better understanding of Non-Suicidal Self-Injury (NSSI) disorders.

The study used a cross-sectional design and involved 314 adolescents and young adults in high school or university. A stratified sampling method was used. All participants filled out the ISAS questionnaire. Data were analyzed for content validity, construct validity, item discrimination value, and internal consistency (Croncbach’s α). The translation process was carried out using forward and back-translation methods.

The ISAS questionnaire consists of section I, the behavioral scale, and section II, the functional scale. For content validity, Aiken's V coefficient obtained for both scale sections I and II is in the range of 0.917 – 1. This result shows that all items on the scale have very good validity. Confirmatory Factor Analyses were carried out using Lisrel 8.80 software on section II, resulting in several goodness of fit values that were not good enough (χ2 = 457.68; P < 0.000; df = 64; χ2 / df = 7.151, RMSEA = 0.130) and several other values that are quite acceptable (CFI = 0.95; SRMS = 0.057; NFI = 0.95; GFI = 0.83). The factor loading from section II ranges from 0.43 - 0.91. The item discrimination value using the corrected item-total correlation of section I is in the range of 0.031 - 0.837 and section II ranges from 0.290 – 0.854. The reliability analysis values in section I and II of the ISAS are α = 0.527 and α = 0.966, respectively.

This is the first study to have validated the Indonesian version of the ISAS questionnaire. The Indonesian version of the ISAS questionnaire is considered a valid and reliable instrument to assess NSSI disorders.

This study aimed to assess the validity and reliability of the complete Persian version of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) in an Iranian population.

In this descriptive study, the TEMPS-A was first translated to Persian by a bilingual expert and was then back-translated to English by another expert and compared with the original version. The face validity and content validity of the Persian version of the questionnaire were confirmed following assessment by several psychiatrists. The Persian version of the questionnaire was then administered among 30 personnel of Imam Hossein Hospital to be completed. The same questionnaire was administered again among the same personnel after a 2-week interval to assess its reliability. 

The Cronbach’s alpha was calculated to be 0.911, indicating excellent reliability of the Persian version of the TEMPS-A. None of the questions required correction or omission. Some questions did not have a good correlation with the general scale but the correlation of the majority of them with the general scale was good. A significant difference was found in the mean scores of the questions (P<0.001), and the mean total score was 1.73.

The present results showed excellent reliability of the complete Persian version of the TEMPS-A (> 0.9). Future studies are required to scrutinize the subscales of this questionnaire.

 Knee osteoarthritis (KOA) is the most common destructive disease of the knee joint. The purpose of the present study was to design to psychometrically assess a checklist for knee care behaviors in housewives living in Yasuj, Iran.

 This study was conducted from 2019 to 2021. Medline, Google Scholar, and SID databases were searched using keywords such as KOA, menopause, instrument, self-care behavior, and women. The first draft of the checklist, consisting of 41 items, was prepared, and 10 experts assessed its wording, content validity index (CVI), and content validity ratio (CVR). Cronbach’s alpha and test re-test were utilized to assess the reliability of the tool.

 Content validities confirmed the 38-item tool with 5 dimensions of standing, sitting, walking, sleeping, and exercise practicing, which were rated on a yes (score 1) or no (score 0) response. The total values for CVR and CVI for the tool were 0.97 and 0.88, respectively. Cornbrash’s alpha and test re-test coefficient of 5 dimensions were above 0.7, which was in an acceptable range.

 The study findings suggest that the 38-item tailor-made knee self-care checklist is a valid and reliable tool. Indeed, this instrument could be used by healthcare providers in health centers for evaluating knee self-care behaviors in KOA-suffered women. Furthermore, this checklist is worthy of use to further help determine the risky behaviors of women while doing daily activities and to design appropriate practical and educational interventions for improving their knee-related behaviors.

The advent of industrialization and the invention of the automobile have increased traffic accidents, impacting the quality of life. The purpose of this study is to evaluate the validity of the safe driving self-efficacy tool using confirmatory factor analysis (CFA) to confirm the factors extracted from the exploratory factor analysis stage and also to evaluate the reliability of this tool.

This study involved 600 individuals residing in Tabriz, aged 20-50 years. The questionnaire utilized in this study was a researcher-made tool and evaluated for structural validity, goodness-of-fit, and internal consistency. Construct validity was tested using the first and second-order CFA using AMOS23 software. The internal reliability of the questionnaire was determined based on Cronbach’s alpha coefficient (α > 0.7).

The study analyzed 589 questionnaires from 600 participants, with a mean age of 35.04 years (SD = 8.367). The majority of respondents had a driving experience and a history of traffic accidents, primarily within urban areas. The CFA also confirmed five factors with 42 questions, which showed positive results. The value of Cronbach’s alpha coefficient for all factors was more than 0.7.

Out of the 60 items in the questionnaire, 42 items were confirmed with appropriate goodness-of-fit indicators. The amalgamation of these constructs within the model effectively measures the concept of safe driving self-efficacy, thereby establishing the tool's reliability. As a result, this survey can serve as a valuable benchmark for evaluating individuals' self-efficacy concerning safe driving practices.

Because of the numerous problems created by neurofibromatosis type 1, particular quality-of-life evaluation measures are quite significant. In Iran, general instruments are used to assess the quality of life of the target group. This study aimed to translate and examine the psychometrics of the Persian version of the Neurofibromatosis Type 1 Adult Health-related Quality of Life (NF1-AdQOL) questionnaire.

This was a methodological and cross-sectional study. A total of 414 adult patients with neurofibromatosis type 1 in the Iranian Association of Neurofibromatosis were selected via convenience sampling. With the permission of the questionnaire's developer, the English version was translated into Persian using the standard back-translation procedure. Validity was assessed using face validity, content validity, exploratory, and confirmatory factor analysis. The reliability and internal consistency of the questionnaire were assessed by Cronbach's alpha and Spearman's correlation, respectively.

The participants' mean age was 34.48±8.3 years. The 31-item questionnaire was translated into Persian, and based on content validity analysis, 2 items were removed. The adequacy of the sample size was acceptable (KMO = 0.940). Exploratory factor analysis revealed 4 factors. The scale had good reliability (Cronbach's alpha: 0.95), and the intraclass coefficient was 0.91. The total mean quality of life score was 93±25.18.

The finding showed that the Persian version of the questionnaire has good structural characteristics and is a reliable and valid instrument for measuring the quality of life of patients with neurofibromatosis 1.
